Fault analysis of marine generators is paramount to improve reliability and accessibility of a marine electrical power system. Inter-turns fault is presumably the most common fault in a PMSM and the symptoms associated with this fault in many machines are undetectable, depending on the level of fault. This paper proposes a novel method to use search coils to determine the inter-turns fault in a Surface...
Induction machines are widely used in different applications. Unpredicted breakdown of these machines usually leads to costly downtime and repairs. These expenses can be minimized by using proper condition monitoring techniques. Eccentricity fault is one of the widespread faults causing machine malfunction; its detection could be useful for preventing of harmful consequences. In this paper, different...
Gearboxes are widely used and subjected to progressive deterioration which makes box condition monitoring a relevant topic in the servodrive industry. This paper proposes a novel scheme for performing integral condition monitoring in a drive containing a gearbox. The proposed scheme is based on a modified MCSA scheme (motor current signature analysis) that uses the drive rectifier input currents instead...
